Celtic rockers Flogging Molly performed a raucous set for a capacity crowd of St. Patrick’s Day revelers at the Boulevard Pool at the Cosmopolitan of Las Vegas on Saturday night. Merging punk rock with Celtic instruments, the band got onlookers to stomp and sing along to hits like “Drunken Lullabies,” “Devil’s Dance Floor,” “Float” and “Salty Dog.”

As a band that cannot be categorized, Flogging Molly’s heart and soul is felt through fifth studio album and most prized work, “Speed of Darkness,” released in 2011. Thirteen years after debut album “Swagger,” the band continues their loyalty to fans, performing in bars, pubs, and nearly every major rock festival in North America, Europe and Japan.
